dt-bindings: iio: light: Simplify interrupts property in the example

dynaimage,al3010 and dynaimage,al3320a are I2C devices, so their
interrupts are not routed to GIC and rarely first interrupt cell is <0>.
This looks like copy-paste from some SoC block, so drop it and also for
readability use known defines instead of hard-coding interrupt flag.
